GitHub allows you to add as many email addresses to your account as you like. If you set an email address in your local Git configuration, you will need to add it to your account settings in order to connect your commits to your account. For more information about your email address and commits, see "Setting your commit email address on GitHub."

In addition to notifications and account emails, GitHub occasionally sends marketing emails with news and information about our products. If you unsubscribe from existing marketing emails, you won't be included in future campaigns unless you change your GitHub email settings.
